* Domains now have a list of owners, which are ``IUser`` objects, instead of
the single ``contact_address`` they used to have. ``IUser`` objects now
also have a ``is_server_owner`` flag (defaulting to False) to indicate
whether they have superuser privileges. Give by Abhliash Raj, with fixes

* Domains can now optionally be created with owners; domain owners can be
added after the fact; domain owners can be deleted. Also, users now have
an ``is_server_owner`` flag as part of their representation, which defaults
to False, and can be PUT and PATCH'd. Given by Abhilash Raj, with fixes
and refinements by Barry Warsaw. (LP: #
